CEMENT-CAN.

SPECIFICATION forming part of Letters Patent No. 758,966, dated May 3, 1904.

Application iled December 30, 1903. Serial No. 187,105. (No mhdel.) Y

To all whom, it may concern.:

Be itknown that I, WILLIAM W. HALL, a citizen of the United States, residingat Boston, in the county of Suffolk,- State ofl Massachusetts, have invented a certain new and useful Improvement` in Cement-Cans, of which the following is a specification, reference being had therein to the accompanying drawings.

My invention has for its object toy provide a suitable and convenient means for the reception and holding of cement, consisting of rubber or other substances in solution in benzin or other suitable solvents. Considerable difliculty has heretofore been found in obtaining a can which will keep the cement airtight, and therefore prevent evaporation, which will not easily become clogged with the dried cement, and which when it does become so clogged may be quickly cleaned. The cans now in use for this purpose are so constructed that it is very diiiicult if not impossible to clean them, and it is common to have the cans become so clogged with cement in a few weeks that they have to be thrown away. The destruction of one of these cans when gummed up with the dried cement involves a considerable loss aside from the loss of the can, because the dried cement has a large value due to the high cost of the materials used in its manufacture. To be satisfactory to the user, the cement-can must also be so shaped that it will not be readily overturned and so arranged that it may be quickly filled. The device embodying my invention doesaway with the aforesaid difliculties and provides a can of an inexpensive construction capable of long-continued use under the most exacting conditions.

My invention will be readily understood from the following description, in which reference is -made to the accompanying drawings, and the novel features thereof are pointed out and clearly deiined in the claims at the close of this specification.

In the drawings, Figure 4l is a section through the center of the cement-can. Fig. 2 is a plan view thereof.

l is a receptacle or reservoir for cement, and Consists of sides and bottom, as shown in the accompanying drawings. It is preferably made of tinof good quality and constructed `with a wire 2 at the top edgeanda iuted bead 3 a short distance below the top edge 21,V

against which the edge of the cover-flange may rest. In practice I make the topedge 2l of the can or barrel slightly less in diameter-than at the point just above the bead 3, for a purpose to be hereinafter further described. I construct the bottom 4 in any well-known manner, preferably attachingl it can 1 the lower edge ofthe sides of the coverv strikes the fluted rib or bead 3 of the can and the upper edge of the can 1 containing the wire 2 strikes against the inside of the top ofthe cover. By the construction just described I obtain a substantially air-tight reservoir for the cement and one which will not leak if the cement-can happens to be turned upon its side. For a similar reason I preferably make the diameter of the cementcan large as compared with its height in order that the danger of upsetting may be lessened as much as possible.

In the center of the cover and preferably secured thereto by solder or the like I provide a'well 8. This well 8 is cylindrical in form and is constructed from a single piece of sheettin. At a convenient point in its sides is a rib 9, around which is placed solder, firmly uniting the well 8 and the cover 5. The well 8 extends downward when the cover 5 is in place on the can, so that the bottom of the well is near the bottom of the can, but does not come in contact with it. This distance between the bottom of the well and' the bottom of the can may be varied to suit the particular kind of cement to be used and the circumstances 'of its use. The lupper part ll0 of the well 8 rises above the surface of the cover 5 a convenient amount and provides a rim upon which asmall cover l1 may be placed. This small cover ll l make, preferably, somewhat larger than the top l0 of the well 8 in order that as the edges of the well become clogged with the cement the cover 1l may still fit over the top of the well and will not adhere too tightly to the said well. This cover' may be made in any suitable and well-known way. I find it convenient to attach this small cover l1 to the edge of the large cover 5 by means of a exible connection or chain l2, having therein a swivel i3 to prevent objectionable kinliings thereof. This chain or connection insures that the cover and can are always together and suggests atleast to the operator that the cover be kept upon the can, thereby preventing the evaporation of the solve-nt from the cement and the consequent deterioration of the cement.

Vln the side of the well 8 l place a vent or hole 1li for the passage of air to or from the maininterior portion of the can or reservoir.

This vent 14 permits the escape of air from the main reservoir l through the well 8 when the cement-can is filled; otherwise the air in the said reservoir would be compressed during the process of filling.

The cement-can as thus constructed is very convenient in use and easy to clean. lt may be readily filled by pouring the liquid cement down the well 8. lV hen the can becomes stuck up with the `cement, as necessarily happens sooner or later, it may be taken apart and its various parts cleaned by scraping or by dissolving the cement in a solvent, thus saving the dried cement, which is of considerable value, and leaving the can in as good condition as if it were new.

lhat I claim ise l. In a cement-can, the combination of a reservoir provided with a cover, a well in the said cover, a Vent or passage forming a communication between the chamber of the said reservoir and the chamber of the said well, and a cover for the said well, substantially as described. 2. ln a cement-can, the combination of a reservoir, a cover therefor, a well in the said cover and having an air-vent through the said well into the said reservoir and a cover for the said well, substantially as described.

3. ln a cement-can, the combination of a reservoir having a constricted top portion for the reception of a cover, a cover with slightly* liaring sides capable of being seated upon the said top portion, a well in the said cover projecting downwardly through the said cover toward the bottom of the cement-can and upwardly above the top surface of the said cover, and having an air-vent through the walls of the said well into the said reservoir, and a cover fitting upon the upwardly-projecting portion of the said well, substantially as described.

4. ln a cement-can, the combination of a reservoir, a cover therefor having a centrallylocated well with an upwardly-projecting portion, a cover for said well, and a Iiexible connection for securing the said cover to the cover for the reservoir, substantially as described.

ln testimony whereof l aiiix my signature in presence of two witnesses.

WILLIAM NV. HALL.
